In the early 80s, beyerdynamic achieved a real milestone in the history of audio technology. The company’s new headphone series with the models DT 770 PRO, DT 880 PRO and DT 990 PRO opened up previously unimaginable possibilities and won the approval of experts in the field. Countless audio professionals worldwide still value the high quality of the materials, workmanship and sound that leaves nothing to be desired.

The DT series was developed to always deliver optimal sound in a wide variety of applications and situations thanks to the various headphone designs for a broad range of environments:

Contact

technical data

Transmission type

Wired

Headphone design (operating principle)

Closed

Headphone impedanceAlso known as nominal impedance. The impedance is the AC resistance of the coils of loudspeakers and headphones in ohms. Since impedance depends on the frequency, it is always specified at a frequency of one kilohertz.

32 ohms

Headphone frequency responseThe frequency response specifies the highest and lowest frequencies reproduced by the acoustic transducer of the headphones.

The beyerdynamic DT-770 is the studio headphone per se! It is extremely robust and fits very tight and secure on the head. It, however, is not the most comfortable of its kind. If you do not wear the headphone each day for hours, it is a good choice.

The DT 770 is circumaural and features a closed design with an excellent ambient noise attenuation making it ideal for monitoring. Its slight bass boost helps unmixed material to achieve better results.

With the beyerdynamic DT 770 PRO 32 Ohm, the manufacturer has made a subtle adjustment to the popular studio headphone - this time it's a pair of headphones, which can be, in fact, loud enough to be operated on mobile phones, tablets, laptops & Co. With this project the 32-ohm version was sent on a mission which it fulfilled perfectly.

As before, this monitoring system scores mainly with a neutral frequency response, however, with the deep bass and the slightly shy low mids the curve appreciably kicks out, but that’s ok for me and is a welcome variety. The attention to detail is very good the highs are present without being shrill. For a headphone with a closed design, the 32-ohm version scores with a good, reasonably “open” spatial sound; on the virtual stage, which extends far, all of the individual sounds can be heard well and separated from each other. The pulse fidelity is exemplary in this price range, short stops come with small drawbacks so fast and brisk, that the sound remains very “disciplined” and never tends to unduly soften the sound.

Even the workmanship of this beyerdynamic model deserves a good score. The construction is still robust and it is even difficult with brute force to harm this headphone. Finally, the high comfort of wearing is to be commended with which even long sessions are completely pleasant.

Pro:Powerful yet controlled bass Very detailed highs without being shrill Very good room image for a closed headphone

Those who are looking for a neutral monitoring headphone for audio recordings, will find a good and reasonable solution with the 32 ohm version of the DT 770 PRO.

With the beyerdynamic DT 770 PRO the German manufacturer from Heilbronn provides a headphone which is suitable for monitoring purposes and for recording studios. Listening to music free from demands on an absolutely exact reproduction is even more fun. The workmanship is good. It is no problem to accept that the ear cups are made of plastic, because the weight is still acceptable. The velour ear pads are great and are not as sweaty as leather. This allows long sessison with a high comfort. The attention to detail in reproduction is really fine and the smooth sound almost free from distortion convinces with bass, mids or highs. Furthermore, the DT 770 PRO impresses with a spatial presentation, which is not often found in this price category. But with this headphone there is still something to blame. If you prefer a completely linear frequency response, the slight overemphasis of the bass will not suit you. The prominent bass frequencies ensure that the mids are slightly moved into the background, what complicates the exact judgement of a mix for untrained ears. All in all the beyerdynamic DT 770 PRO is a great headphone, which we can recommend with a good conscience.
